!!! Threshold limit exceeded

'''Event''': E_CORE_THRESHOLD

This event is triggered when a particular action takes longer than a specific threshold. It can be raised when a MySQL or DNS query takes too long, or a SIP message processing goes beyond a specific limit. For more information please see [[http://lists.opensips.org/pipermail/users/2011-February/016918.html | this]] post.

Parameters:
* '''source''': the source of the event: mysql module, core (for DNS or message processing warnings).
* '''time''': the number of micro-seconds the limit has been exceeded
* '''extra''': extra information, depending on the source of the event

!!! Private memory threshold exceeded

'''Event''': E_CORE_PKG_THRESHOLD

This event is triggered when the private memory usage goes above a threshold limit, specified by the '''event_pkg_threshold''' the core parameter. It warns external applications about low values of free private memory.

Parameters:
* '''usage''': the percentage of private memory usage. Can have values between '''event_pkg_threshold''' and 100.
* '''threshold''': the '''event_pkg_threshold''' specified in the script.
* '''used''': the amount of private memory used.
* '''size''': the total amount of private memory.
* '''pid''': the pid of the process that raises the event.

Parameters:
* '''usage''': the percentage of private memory usage. Can have values between '''event_shm_threshold''' and 100.
* '''threshold''': the '''event_shm_threshold''' specified in the script.
* '''used''': the amount of private memory used.
* '''size''': the total amount of private memory.
